7、15电动油泵YBZ2*2/5022006.11.13合计61五、施工工艺及施工方法(一)施工准备1、预制梁场位置选定及平面布置根据现场实际情况,某桥T梁预制场位于某桥南平台侧的路基上。该段原为山丘,开挖压实整平后再用砼将梁场全部硬化硬化厚度不小于10cm。预制厂平面布置包括预制台座、运梁道路、存梁场、龙门吊及走行轨道、钢筋加工棚、砼拌和站、现场办公场所等。具体布置见图5-1、5-2。2、台座设计大分洋梁场制作4个40米梁台座,T梁台座采用变宽与中间平直段台座和两端头钢筋砼浇筑的施工方法制作,包括垫层、砼整体台座、纵向角钢、底模钢板和端头钢筋砼五部分。垫层和砼台座均采用C20砼,垫层砼厚度为15
8、cm,砼台座厚度为50cm,砼台座内每40 cm 设两根12mm竖向预埋筋和两道12mm横向预埋筋,在竖向预埋筋顶部焊接5.0*5.0cm角钢,台座底部每50cm预埋100mm PVC管用于穿加固侧模对拉螺栓之用。台座浇注完砼后在5.0*5.0cm角钢顶面平铺8mm厚T梁底模钢板,钢板与角钢焊接牢固,横向板缝满焊,焊接处均采用砂轮机打磨平整。台座两端头采用钢筋砼基础,台座顶面采用5.0*5.0cm角钢预留出预埋钢板调平层,以此满足因梁长变化预埋钢板位置变化的施工要求。台座侧边角钢上贴好5mm的海绵带,台座两端按设计位置做好预埋钢板槽,并在其后侧预留出张拉缩缝1cm,且用橡胶板填平实。预制台座应
9、设置向下拱度,其值大小以水泥混凝土铺装前梁的上拱度(向上)不大于2cm,同时满足成桥后预拱度(向上)要求控制。设计反拱度值35mm仅为参考值,具体反拱度值应在施工时先行按照参考的反拱度预制一片并进行张拉后确定,并可根据实桥多片梁预制情况予合理调整。确定反拱度时还必须考虑在存梁时间内的预拱度继续发展的可能。 3、T梁模板制作:底模直接以台座顶面钢板作底模。侧模采用大块平合式钢模,根据梁长或隔板位置分成数个单元模扇,外模架板用6mm 钢板模压成型,水平肋、竖肋用10#槽钢制成,竖向加劲肋用10mm厚的钢板制成,钢支架为10#槽钢。Opinions and suggestions on the pa
